FYI, this is not the official installer. It's similar to that one, but not quite the same. > - Tools->Tex_Information->Latex_styles does show "biblatex.sty".

One suggestion would be to try with a fresh user directory. It's possible there's something in the one you have that's left over from the previous biblatex hackery. But it's hard to know. Riki
